GPU MODELS / ALTERNATIVES TO MI325X
Alternatives to the MI325X
The MI325X is the memory-maximized refresh of the MI300X: same CDNA 3 compute, a third more HBM3e at 256 GB. It exists for one reason - holding larger models on one GPU - and where clouds list it, that is exactly the pitch.
People usually compare the MI325X against MI300X, H200 SXM. Prices below are live on-demand published rates from the panel.
LOADING LIVE DATA...
| Alternative | Memory | Bandwidth | Cheapest live rate | Head to head |
|---|---|---|---|---|
| MI300X | 192 GB HBM3 | 5.3 TB/s | - | MI325X vs MI300X |
| H200 SXM | 141 GB HBM3e | 4.8 TB/s | - | MI325X vs H200 SXM |
WHEN EACH ALTERNATIVE WINS
MI300X
Same compute with 64 GB more memory. For models that fit in 192 GB they are identical - pay for the 325X only when the model demands it.
H200 SXM
The H200's 141 GB is the CUDA-ecosystem answer to large-model serving. The MI325X nearly doubles the memory; the trade is ROCm versus CUDA.
MI325X ALTERNATIVES - FAQ
What is the best alternative to the MI325X?
It depends on the workload. MI300X: The MI300X is AMD's serious answer to Hopper: more memory (192 GB) and more bandwidth (5.3 TB/s) than any NVIDIA part before Blackwell, at panel prices that frequently undercut H100. H200 SXM: The H200 is an H100 with the memory subsystem rebuilt: 141 GB of HBM3e at 4.8 TB/s versus 80 GB at 3.35. Live rates for each are in the table above.
Why look for MI325X alternatives?
Small workloads - this is frontier-class capacity.
How much does the MI325X cost compared to its alternatives?
Each alternative's current cheapest published rate is listed in the table above; figures recompute hourly from provider-published prices.
